Consequently the edge receives the coloring oriinisliing substance or preparation ifrom i the outlet'in being thus:fed.

The ypassage aintersects the said c'hs'tniben'y so vthatthe. coloring.y or* vfinishing substance or preparation,.1receivedlWithin tion'edquantity, and` may Iadopt any 'oftvari-V ous forms offorcefeed devices suitablefor the purpose.'l The i illustrated'machinefcontains a 'preferred form of vmeans offsuch class,' comprisinga needle-plunger c lwhich occupies the passage a and fis-givenfendwisereciprocating movements thereinw Insuch movements the plunger cause/5,:orrv iassistsfin causing; the coloring Tor finishing;l substance or=`preparationv to issue at'tlie' outlet fai, and in addition lprcventsclogging# of the i rp8S` sage and Sroutlet. The means-roffimparting thereciprocating movements tothe plunger c may be varied Ainepractice.Herein,-z.the said means comprises a rotating cam `cff'on thecountershaft'cl at thefrearsofwthe.fm-af chine. i' and connectionsbetween tlie-.fpl'unger andthe 'said cam.v7 Such connectiglonsconsst inthis* particular: instance"y off.: a1 plunger 6; a rod "cthavingfone endthereof connected Y endofthe said v rod isf connectedjland alberi-Zontal arm extending rearwardly beneath cani c and furnished with a ribcX shown best in Fig. 8, Sheet 2, against which said cam acts. The saidbell-crank or rocker c5 is mounted between center-screws 050, c5, inconnection with npst-anding supports 051, NH and is adapted to swing ina Vvertical or substantially vertical plane, in the direction from frontto rear of the machine and vice versa. A spring c7, Figs. 2 and El, actsupon it oppositely with respect to the said cam to keep the rib cX incontact with the cam or the adjacent portion of the shaft d. It rocks inthe said vertical plane upon said center-screws c5", 050, when actuatedby the cam and spring, and by means of the rod of transmits movement tothe bell-crank c2 so as to swing the latter and thereby cause theplunger e to reciprocate endwise within the passage a.

Preferably, the devices for ensuring feed of the coloring or finishingsubstance or preparation are contrived to operate as a lil) force feed,and the retracting inoz'en'ient of the plunger c is made sufficient inextent to withdraw its leading end into the chamber a* so as to afford`opportunity for the said substance or preparation to flow from thechamber into the portion of passage entending from the chamber to outletc. In the projecting stroke of the needle-plunger, its leading endforces a small quantity of the coloring or finishing substance orpreparation ahead of it through the said portion of the passage a, tothe outlet a, said end reaching in such stroke a point close to theposition of the edge of the material operated upon. This action causesthe said quantity of the said substance or preparation to be deliveredto the said edge closely adjacent the point at which the latter issubjected to the action of the tool.

The reciprocating action of the needleplunger takes place with suchrapidity that a continuous supply of the coloring or 'linishingsubstance or preparation is ensured at the outlet a.

The use of a reciprocating needle-plunger is especially advantageouswhen employing a viscid quickly hardening substance or preparation7 suchas a solution of Celluloid in amyl-acetate. The said device ensures aregulated feed at the outlet c and prevents the passage a and the saidoutlet from becoming clogged.

The avoidance of waste of the fluid .subn stance or preparation employedis attained in the illustrative machine through providing for control ofthe feeding of the said substance or preparation so that no feedingthereof shall take place in the absence of material to be operated upon,and so that feeding shall begin when a piece of such material is inposition to receive such sub` stance or preparation.` shall continuewhile .the said 4piece is such pesitiein and 'shall in this instance thepresser or hold-down i410,

although in some cases it may be another piece specially employed as adetector. rthe presser l() is movably supported in the machine by meansof a presser-carrier al supported by a mounting llh Figs. l and 2, thatis pivoted by meaiis of center-screwa 4t2, e2, upon the lined frame-part22 with capacity to swing in a vertical plane so as to allow the presserto move to accoinniodate itself to the material when the leading end ofthe "r latter is inserted under 'the presser, and so as to provide fordrnvnvard movement oi.' the presser when the material passes out; fromunder the presser. il, coiitracting.;- coiled spring all, Fig. l,connected with the presser-carrier holds the presser-carrier and pressertoward the surface of annulus l0, yields to permit the presser to beseparated from the said surface by the entrance of a piece of materialbetween the two, and draws the presser toward the said surface when thematerial passes out from under the presser. rl`he position of thepresser or other detecting member determines whether there shall befeeding of the coloring or lininshing substance or preparation, or thefeeding shall be suspended ln practice, various arrangements may beemployed for causing the feeding to begin when the presser is separatedfrom the annulus. continue while the pressure remains separated from theannulus, and cease when the presser moves toward the annulus again.Herein such action is provided for by mounting the bell-crank or rockerc3 upon a laterally-movable carrier constituted by an upright arm 072.llie .said carrier arm is made laterally movable by being pivotedbetween center-screws c5". c5. on a supporting carriage Q and itslateral in ementl taking place under the control of the presser or otherdetector are adapted to place the bellcrank or rocker either in workingrelations with the cam o or out of working relations with the latter.Normally, the carrienarin is caused by the tension of a contractingcoil-ed spring m, Figs. l and 4, to occupy a position toward the righthand side in F l, 3 and 4, in which it presents the rib cx, (Fig. 8) oftheI hoi-is arm of bell-crank or rocker to a con itric or sabstan fconcentric portion of the earn o' or rotan Y shaft al as in Fig. fl. @olong as the paw i occupy the position `inst referred to the ben- ,cranlser rocker is out @t working rela/tiens lOl) cam-portion of the Vpropereccentricity or throw, the desired length oi stroke is secured. Thisregulation is effected herein by shitting the acting end oi' the core otthe electro-magnet g in the required direction, so that when thearmature 7c has been attracted by the energized magnet and moved towardthe latter, accompanied by upstanding arm 052 and bell-crank or rockerc5, this action will carry the bell-crank or rocker either 'fartherlengthwise oi the cam or not so far, as the case may be, and therebyplace the horizontal arm oi the bell-crank or rocker in. workingrelations with the portion ot the cam which will give such length oitstroke. Gompensating adjustment of stop a will be made, ii necessary, topermit the spring m to return the bell-crank or rocker back to theportion ot least throw oit the cam, or the concentric portion of the camor of the shaft d. This shift ot the acting end of the core of th-eelectro-magnet is provided Jior in the present instance by maltingcarriage C adjustable transversely of the machine, so that by suchadjustment off the carriage the electro-magnet in its entirety embracingthe core is thus shifted. Herein, the said carriage is pivoted by meansof a screw CX to bed-plate 12 so as to adapt it to be swung transverselyabout such screw. An arm Cy of the carriage is extended to the tront ofthe machine to serve as a convenient handle that may be, used by theoperator for swinging the carriage in making required adjustments of thecharacter just explained. I provide for varying the point reached by theplunger in its down stroke. That is to say, the closeness or" 'approachof the end oi' the plunger to the outlet. ln the present instance therod c is made adjustable lengthwise. Its rear end occupies a holethrough a connection-piece c41 that is pivotally connected to theupstanding arm oi bell-crank or rocker c5. After loosening thebindcrscrew 042, Fig. 2, which astens the rod c4 to theconnection-piece, the rod may be shifted lengthwise to the necessaryextent and then be secured in the position oi relative adjustmentthereby attained by tightening up the said binding screw.

Referring now yto annulus The mounting 10b and annulus in this instanceare yieldingly upheld by a sp 1ing 18, Fig. 1, upon which the.intermediate portion of the mounting rests. The lower blade or leaf ofthe said spring rests `upon a nut 13a upon a threaded stem 131? risingfrom the bed-plate 12. Through adjustment of the nut up or down upon4the said threaded stein, the tension of the spring, and thereby theresistance which the. annulus Oilers to being depressed by work enteringbetween it and the tool 20, may be regulated; and thereby the degree ofthe force with which the work is held in contact with the tool, and theefect produced by the tool upon the work, may be regulated. The .springmay be omitted it desired, as in the prior Letters Patent, and the nutalone be utilized to adjust the mounting and annulus up or down.

As a means of adjusting the closeness of approach of the working surfaceof the annulus 10 to the tool, to suit diiferent thicknesses of stoel;operated upon and vary the results secured upon th-e stock, I haveprovided the illustrated machine with an adjusting screw t, Fig. 1,applied in connection with a- Xed portion ot the machine-traine, saidscrew being arranged horizontally and having a conical end which engageswith the upper side of an end portion oit the mounting 10l for theannulus. The action of spring 13, in pressing the mounting upward so asto lzeep the annulus up close beneath the tool, keeps the saidend-portion oi the mounting in contact with the said conical end of theadjustment-screw. Such conical end constitutes a stop which delines thecloseness oit approach ot the working surtac-e of the annulus to thetool. Adjustment of the screw end\.vise varies the said closeness ofapproach, according as larger portions ot the cone are presented inposition i'or the end-portion of mounting 10b to engage therewith or arewithdrawn so that smaller portions oi the cone are presentedin suchposition.

l provide for preventing portions of the material operated upon frombeing carried down at the inner periphery oit annulus 10 by the actionoi' the tool 20, so as to produce a feather edge, by mounting theannulus so that it shall be movable toward the guide or gauge for thematerial-edge, and causing the said inner periphery to bear against thesaid guide or gaugeand extend across thel radial face, a, oi the tool,close to the said face. As described earlier hereu in, 'the edgeguide orgauge is` constituted by the end-surface of the casing a2 adjoin-:

ing the tool. lt surrounds the periphery of the radial tace '20a ot thetool. rlhe said inovability of the annulus is secured by providing i'ormovement of annulus-carrier 10a transversely, in the present instance bypivl oting foot ot the annulus-carrier by means of center-screws s, Fig.l, to the said mounting, and herein the inner periphery of the annulusis caused to bear against the said endsurtace by the tension of acontracting Vcoiled spring s which is engaged with the annulusrarrier.The casing a2 is mounted upon the tree end of the fixed frame-part 22through which the tool-shaft extends. lt is iixed adjustably in itsworking position by convenient means tor the purpose. llore in aclamping screw a, Fig. 5, is employed. In practice the said casing isadjusted laterally into a position in which it holds the inner peripheryot' the annulus just clear during the presence of the material, andsuspendingits movements in the absence of the material.
